Company using SCR technology to meet tough emission regulations. D.E. Moore and J. VandenPlas. Pipeline Gas Ind., December 1998, 81(12), 61--63.

The feasibility of installing natural gas driven compressors at a pumping station in New Jersey is discussed. Selective catalyst reduction (SCR) technology is used to ensure compliance with legislative requirements. Multiple inbound and outbound pipelines and extensive storage facilities are involved. The pumps deliver approximately 200 000 gal/day of refined petroleum fuels to Long Island terminals and to New York airports. Pumps driven by natural gas are less costly than those driven by electric motors. The SCR process involves selective reduction of NOx by ammonia. Chemical reactions are illustrated and reaction conditions are summarized. Capital costs are reviewed.
